Of course the respironics brand 12volt cord has everything that is needed. They make the machine, they make the cord, it would be ludicrous to think that their own cord, for their own machine, wouldn't work.
Because it is not an official Philips cord. It is false advertising. It is not fully compatible with DreamStation.palerider wrote: ↑Fri Aug 10, 2018 3:16 pmWhy should there be a disclaimer on the product listing for the official respironics cord for the respironics dreamstation?

Perhaps because of this:

I should probably point out that Philips Respironics has already joined the ResMed proprietary club with the introduction of the DreamStation line.
They use they same type of plug (same dimensions, but right angled) as the A10 but they use a simple 20k ohm resistor to +12V on the center pin.
some testing with a power supply and a decade box shows the DS needs to see between 18.9K to 26.2K to power up and run without an error screen. The blower will not start with the wrong resistance.
Outside barrel of plug is Ground
Inside Barrel of plug is Positive
Center pin is positive.

Because the manufacturer of the Freedom battery said I need to proprietary DreamStation 12V adapter cord to get full usage of the battery charge. The regular shielded DC DreamStation cords do not work when the battery is on the lower end, so it will only be partially usable.palerider wrote: ↑Fri Aug 10, 2018 4:02 pmWhy do you say the one you bought isn't "fully compatible" with the dreamstation?mileena wrote: ↑Fri Aug 10, 2018 3:24 pmBecause it is not an official Philips cord.

Whether you believe the people trying to sell you the "extra special" cord *they* make or not, is up to you.mileena wrote: ↑Fri Aug 10, 2018 11:18 pmBecause the manufacturer of the Freedom battery said I need to proprietary DreamStation 12V adapter cord to get full usage of the battery charge.

It's not THEIR fault you bought the battery you did.
That's not how it works. The dreamstation, just like many *laptops* requires a signal from the power supply telling it what kind of power supply is being used. That's *all it is*, it has nothing to do with low battery voltage.
If there's any truth to the "up-sell" claim of the BPS power cord, it may be that as the voltage drops on the 12v battery, the voltage may also drop on the signal. When that drops below the trigger level, the pump shuts off. Powering down when the voltage goes below some level is the proper thing on a lead acid battery where you don't want to go below about 20%, but with lithium you can take it lower. BPS may be holding the signal at a higher level to squeeze out an extra 10% or so from the battery. I have way of knowing the truth here - perhaps Mileena can do a test.palerider wrote: ↑Fri Aug 10, 2018 11:45 pmIt's not THEIR fault you bought the battery you did.

The Respironics cord, which you bought, was designed to work with a 12v battery, such as the ones that CapnLoki suggested you buy. It wasn't specially designed to work with your battery.
The real issue is "why is your supposed 'cpap battery' unable to provide power to the cpap without an extra 70$ cord?"
You seem to be terribly confused about what you've got, and what BPS is trying to sell you.
You bought a Philips Respironics Dreamstation. You then bought a Philips Respironcs 12v cord. It's made by PR, for your machine to be used on a 12volt source.
The 'special cord' from BPS is NOT made by PR, it's made by BPS.
You're bent out of shape because the *manufacturer* of the CPAP isn't custom designing their product to cater to some third party after market product.
So it is the DreamStation CPAP device itself which requires that a DC cord to be able to deliver the proprietary signal, regardless of the source, be it a Freedom travel battery, or a 12V AGM battery.While Respironics DreamStation series PAP devices operate from 12V direct current the DC input port on these devices require a proprietary signal in order to recognize a valid power source; therefore, a 12V power adapter is required to complete the connection between the device and the Freedom™ CPAP Battery.
It is their fault if they advertised falsely, which they did.palerider wrote: ↑Fri Aug 10, 2018 11:45 pmIt's not THEIR fault you bought the battery you did.

I'm also a bit skeptical on the claim that pressure 13 uses no more power than 10. Although PR doesn't publish numbers, the Resmed numbers (and others I've seen) indicate about 20% extra load for that pressure. Although its not a huge difference, its probably more than the up-sell power cord could give.
And the 2 extra hours to recharge from one charger don't quite make sense; if they really put out 6.75 amps there should be plenty of juice. Going from 0 to 50% should only take 2 hours, after that its tapering off so the total amperage available doesn't count. If they said an extra hour I might believe it, but this sounds like another up-sell. Again, I'm hoping mileena can report back.
Nobody advertised anything falsely. You need to get that notion out of your head.mileena wrote: ↑Sat Aug 11, 2018 12:44 pmIt is their fault if they advertised falsely, which they did.
The DreamStation requires a proprietary signal for DC inputs. That is quioted from BPS in my post above. A regular shielded DC cord for DreamStation that all these companies advertise will work, but won't be able to tap the full power from the battery.
*ALL* cords that work on the dreamstation have the 'proprietary signal', otherwise the cord would not work. You're getting confused by the marketing people at BPS... they like that, because they can sell you more overpriced things.
I guess we will have to agree that we disagree then. I respect your opinion. I just wish the companies would have stated their product does not have the need proprietary signal needed to get full usage out of a lithium battery, like Freedom by BPS. It is good for lead acid batteries, but not other types. Now I have a useless adapter.palerider wrote: ↑Sat Aug 11, 2018 1:40 pmNobody advertised anything falsely.
